The invention relates to a hydrogenated nitrile-butadiene rubber composition. The composition comprises hydrogenated nitrile-butadiene rubber, butadiene rubber, an anti-aging agent MBZ, an anti-aging agent DDA, mixed gas carbon black, quick pressed-out carbon black N550, dioctyl adipate, dioctyl sebacate, dicumyl peroxide, triallyl isocyanurate, selenium diethyl dithiocarbamate and gamma-amino propyl triethoxysilane. The low-temperature resistance of the hydrogenated nitrile-butadiene rubber is further enhanced by using the hydrogenated nitrile-butadiene rubber and the butadiene rubber together under the combined action of auxiliary agents such as the dioctyl adipate, the dioctyl sebacate and like; the hydrogenated nitrile-butadiene rubber has the brittleness temperature of up to -56 DEG C, no breakage and still good oil resistance; and other performance of the rubber is not changed obviously. The low-temperature resistance of the hydrogenated nitrile-butadiene rubber is improved and simultaneously the use value of the rubber is improved, which has great significance for better use of the hydrogenated nitrile-butadiene and products thereof in automobile industry, petrochemical industry and the like. Moreover, the safety insurance of the products is improved and the service life of the products is prolonged.
Description
technical field [0001] The invention relates to the technical field of rubber, in particular to a cold-resistant hydrogenated nitrile rubber composition. Background technique [0002] In recent years, with the advancement of rubber products for automobiles, nitrile rubber is changing to materials such as acrylic rubber and hydrogenated nitrile rubber. Hydrogenated nitrile rubber is widely used in automobile industry, petrochemical industry and other fields due to its excellent comprehensive properties. [0003] Hydrogenated nitrile rubber is a highly saturated elastomer obtained by special hydrogenation of nitrile rubber. Hydrogenated nitrile rubber has good oil resistance; and because of its highly saturated structure, it has become one of the rubbers with excellent heat resistance, excellent chemical corrosion resistance, ozone resistance, wear resistance and other comprehensive properties. At present, it has been widely used as a general-purpose oil-resistant rubber in ...
